Ecommerce SEO issues can hide behind a store that looks perfectly usable. Search engines may miss product pages, index unwanted URLs, or struggle with slow templates. Start by checking how search engines access and process your site, then focus fixes on pages that matter to customers and sales. You do not need to change everything at once. A repeatable audit helps you identify the cause, prioritize the impact, and confirm whether each fix works.
Check crawling and discovery
Begin with Google Search Console’s page indexing report and URL Inspection tool. Look for important product or category URLs marked as blocked by robots.txt, not found, redirected, or crawled but not indexed. Inspect a few examples from each group. Confirm that the page loads, returns the expected status, and is not accidentally blocked by a robots directive or login requirement.
Next, review your XML sitemap. Include only canonical URLs that return a successful response, and remove redirected, deleted, or noindex pages. Check that important categories link to their products and that products have a path back to relevant categories. Fix broken internal links and avoid relying on site search or filters as the only way for search engines to discover key pages.
Verify indexation and canonical URLs
A page can be crawlable but still absent from search results. Use URL Inspection for representative product and category pages to see whether Google has indexed them and which URL it selected as canonical. Compare that result with the canonical tag on the page and the URL listed in your sitemap. A mismatch can signal conflicting instructions or near-duplicate pages.
Check that pages you want indexed do not carry a noindex directive, and that canonical tags point to the preferred, live version—not a redirect, error page, or unrelated category. Keep genuinely useful pages available to customers. For discontinued products, choose a relevant replacement or category when one exists; otherwise return an appropriate not-found or unavailable status rather than sending every old URL to the homepage.
Control duplicate content
Store filters, sorting options, tracking codes, and product variants can create multiple URLs with very similar content. Search a sample of URLs in your analytics, crawl data, or Search Console reports for patterns such as question marks, alternate sort orders, and repeated product pages. Decide which version should appear in search, then make internal links and canonical tags consistently point to that version.
Do not block every filtered URL without checking how customers use those pages. Some filtered combinations may serve a distinct search need, while others add little value and create crawl clutter. For low-value combinations, limit crawl paths and use appropriate canonical or noindex instructions based on your platform and SEO setup. Give each important category and product page clear, useful copy rather than copying generic descriptions across many URLs.
Find and improve slow pages
Test key templates—not just the homepage—with PageSpeed Insights and Search Console’s Core Web Vitals report. Check a product page, a category page, and a mobile view. Look for oversized images, slow server responses, excessive scripts, and content that shifts while loading. Test more than once, since connection quality and page conditions can affect results.
Start with changes that improve real shopping tasks. Resize and compress product images, serve appropriately sized versions, and avoid loading below-the-fold images immediately. Remove apps or scripts you no longer use, and review whether essential third-party tools can load later. After changes, retest the same templates and check that image quality, add-to-cart behavior, and checkout still work.
Keep a record of the URLs you checked, the issue found, the change made, and the result. Revisit priority pages after search engines have had time to recrawl them, and investigate recurring patterns across templates. If the source is unclear or the fixes affect a large catalog, Harbour SEO can help you plan a focused ecommerce audit.
